IMPRQVEMENT IN `WOOL-WASHING MACHINES.

Specification forming part of Letters `Patent N 0. [74,005, dated February 22, 1876; application filed December 16, 1875.

To all whom it 'ina-y concern:

Be it known that I, J osIAH K. PRoCTOR,of Philadelphia,in the county ofPhiladelphia and State of Pennsylvania, have invented certain new and useful Improvements in Wool-VVashing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification, in which- Figure lis a perspective of my invention. Figs. 3 and 4 are plan views of the cam-grooves, which give a fixed and uniform motion to the teeth on the forwarding and lifting carriers. Fig. 5 is a side elevation partly broken away. Fig. 6 is an end view partly in section, showing the squeeze-rolls and their bearings; Fig. 7, detail View..

The primary object of my improvements is to obtain a continuous feed or unvarying onward motion of the stock throughout the entire length of the bowl of the machine from the moment it is admitted until it is delivered to the squeeze-rolls, and to accomplish this by means of rotatin gor revolving carriers or forks, havin g teeth hung upon revolvingshafts, which Vare controlled in their movements by camgrooves or cams, in lieu of the reciprocating devices heretofore employed, havingan intermittent motion.

A further object of my invention is to cause the carrier by which the stock is advanced to the lifting-carrier to move said stock through the bowl in a horizontal plane instead of in the arc of a circle, by means of teeth hung upon revolving shafts, which are controlled in their roll.

`A still further object of my invention is to provide means whereby the wool, after heilig lifted out of the liquor, will be prevented from sliding back into the same, and whereby the intermediate carrier, heretofore required between the forks and squeeze-rolls, is dispensed with.

A`still further object of my invention is to provide improved means for squeezing the cleansing-liquor from the stock, the same consisting. in the employment of a cushioned roll held down by means of sp1-ings on its journals.

Referring to the accompanying drawing, A

shows the bowl of the machine, having a false bottom7 B, and'curved inclino B. C and C are the squeeze-rolls, one of which-by prefv erence, the upper one-is constructed as follows: c represents an iron shaft, to which are v which the stock is raised out of the liquor in the bowl and delivered to the squeeze-rolls. This carrier is composed of the heads D D',

affixed to a shaft, d, and provided with revolv-` ing shafts di, in which are rmly fastened L- shaped teeth d2. To one end of the shafts d* aresecured crank-arms d3 d4, having anti-fric` tionrollers d5 d6, which move in a oamgroove,

E, formed in or upon the adjacent side of the bowl A. This cam-groove is so shaped that from the point f to the point f. the teeth d2 will move at or about right angles to th'e bot Vtom vand incline. -As soon, however, as said teeth have reached the point f they begin to assume a vertical position, so as to more readily draw out of the Stockdeposited by them on the chute b, which descends from the upper Y end ofthe incline B toward the squeeze-roll C. This movement of the teeth is rendered positive by means of the roller d5 on the arm d3 entering the offset c2, causing a partial revolution of the shaft dl. In other words, from the moment the roller d5 enters the cam-groove E at c the arm d3 moves in advance of the arm d4. When the roller d5 strikes the'shoulder e1 the shaft d1 is revolved, said roller passing into the oifset e2, and the arm d4 then moves in advance of the arm d3, until the roller d strikes the shoulder or cleat c3, producing another partial revolution ofthe shaft d1 and bringing the arm d3 again in advance ofthe arm d4. The partial revolution of the shaft d1, caused by the contact of the roller d6 with the cleat e3, brings the teeth d2, as they descend, into a nearly horizontal plane, so as lthe better to press the stoel; under them. The entrance of the roller d5 into the cam-groove E at e restores the teeth d2 to the position shown in full lines in Fig. 2. G represents the carrier, of which one or more may be employed, and by means of which the stock is forwarded to the liftingcarrier after being` fed into the bowl upon the roller H and beneath or back of the grating I.

This carrier is constructed and operated substantially like the lifting-carrier, the form, however, of the cam-groove K, by which its shafts and teeth are moved, being diferent from that of the cam-groove E, so as to cause its teeth g to pass vertically, or nearly so, into the grating I, to sweep along the bottom of the bowl in a straight line or horizontal plane, and to draw out of the. liquor vertically. The grating I,is for disintegrating the lumps of stock drawn through it. The lifting-carrier D raises the stock from the liquor in the bottom of the bowl, and deposits it at once in a thoroughly saturated condition upon the chute b, thus dispensing with the intermediate earrier heretofore required between theI liftingfork and the squeeze-rolls, and avoiding all possibility of the stock4 sliding back into the bowl, to obtain which result retaining-pins on the incline, or equivalent devices, were heretof'ore regarded as necessary.

The cam-grooves E and K' give a positive action to the teeth of the carriers, enabling them to do their work more effectively than if permitted to swing loosely oroperate by gravity, controlling the desired positions for said teeth in a manner not possible to be attained by mere gravity.

Instead of L-shaped teeth, crank-shafts having straight teeth, as shown in Figs. 5 and 7, may be employed. Y

What I claim as my invention is- 1. A wool-washing machine, in which the stock is passed through the bowl by means of a revolving carrier. or carriers, the teeth of which are hung upon revolving shafts, and

controlled in their movements by cam-grooves,

4. In combination with the incline B and the y chute b inclining in the opposite direction or toward the squeeze-roll, a lifting-carrier, which raises the stock out of the liquor and deposits it upon said chute. so as to dispense Withan intermediate carrier and prevent said stock from being washed back into the bowl, substantially as shown and described.

5. In a wool-washing machine, a cushionroll, composed 0f a central metallic shaft, c, and wooden segmental sections c1, in combination with bearing-springs c, substantially as shown and described. v

In testimony that-I claim the foregoing I have hereunto set my hand this 14th day of December, 1875.
